High heat flux generation in electronic devices demands new modes, methods and structures to dissipate heat effectively. We investigate the thermal performance of cellular structures using computational fluid dynamics (CFD) and obtained an optimal cellular structure for effective heat dissipation. Then, we validate our numerical results with experimental results obtained using optimized cellular structure. We found the minimum base temperature for the optimized cellular structure to be 43.6 °C and 47.4 °C numerically and experimentally respectively at inlet velocity of 10 m/s. We carried out experiments and simulations at the heat flux of 35,503 W/m2. We found a close agreement between numerical and experimental results with an error of 8.71% for the base temperature. Previously the best base temperatures were reported to be 55 °C and 40.5 °C using air and water respectively [1, 2].
